Now it is very responsive when changing to the next gear. Also my idle is alot smoother as well as the power curve.One thing I noticed is that the outlet of the BOV was a little dusty which could possibly mean some dust could and would have been 'inhaled'.My guess is that the intake pipe now does not loose its pressure when releasing that throttle, even though the turbo probably slows down quicker, it spins up quite fast and the pipes already have good pressure.This is my POV and do not wish this thread to end in debates. The reason I have done this is that many people are running no BOV with a lot of ks with no damage. Once many turbos start failing then I might change my mind.CheersAdrianPS. Its not hard to do so try it yourself and tell me about your findings. Link to comment Share on other sites More sharing options...

Simon from Nizpro put up a great write up on their function a while ago. Have a search for it. Good read. Basically its more of an emmissions thing...

Posted 04/09/07 04:48 AM Share Posted 04/09/07 04:48 AM you could have just blocked the little vacuum hose comming out of it instead of taking it off... helluva lot easier and has the same effect Link to comment Share on other sites More sharing options...
